✦ Synopsis

The possible importance of ground-state destabilization as the origin of the enhanced reactivity of n-nucleophiles is critically examined and it is concluded that, in general, this factor will contribute only slightly, if at all, to the manifestation of u-effects.

Swmnary -The reactivity of the anion of a,a,a-trifzuoroacetophenone oxime towards pnitrophenylacetate is considerably enhanced relative to that of the simiZarZy basic p-chZorophenoxide anion on addition 0-f Me2S0 to aqueous solutions. This is shown to be due to an enhanced stabiZization of the trans
